In American culture, most women, as well as a number of men, have their ears pierced. In recent years, many get other body parts pierced as well. Though people might pierce their bodies for any number of reasons, body piercing is biblically a mark of slavery (Ex 21:6). Slaves had their ear pierced to identify them as lifelong slaves (Ex 21:6). It's even possible that Satan may be using the proliferation of body piercings as part of his plan to make people his lifelong slaves (Heb 2:14-15; see also Rm 6:16, 17, 19).
If you've had your body pierced by a piercing gun or tattoo needles, Jesus identifies with you. He has pierced hands and feet (Ps 22:17). His side was pierced with a sword (Jn 19:34, 37). "He was pierced for our offenses" (Is 53:5). No one has been pierced as painfully as Jesus has been. When people look at your piercings, they might admire them or stare at you, but when people look on Jesus' piercings, their hearts are pierced, and they mourn for their sins (Zec 12:10). Jesus' piercings have power to change hearts.
Instead of looking at your own body piercings or those of others, look on the pierced Jesus. Let your heart be pierced with love for Him. Then offer your body to Him as a living sacrifice (Rm 12:1) and a weapon for righteousness (see Rm 6:16, RNAB). Jesus, pierced for our transgressions, make our hearts like Yours.
